The thermal conductivity of diamond is five times higher than that of copper. It is an excellent material for making heat sinks, and its performance is much better than traditional materials.

Take the lead in conducting diamond gallium nitride research and provide the most complete solutions for diamond gallium nitride production such as GaN on diamond and Diamond on GaN.

Provide 2 inches/4 inches silicon-based aluminum nitride film, sapphire-based aluminum nitride film and diamond-based aluminum nitride film
Coming soon, stay tuned!
